摘要： A switch embedded integrated circuit for battery protection includes a first pin to be connected with one terminal of a battery, a second pin to be connected with a load or charger, a third pin to be connected with another terminal of the battery, a MOSFET having a body diode thereof and connected between the first and second pins, a control logic circuit and a detection circuit. The detection circuit monitors the voltage between the first pin and the third pin to determine a detection signal for the control logic circuit to turn on or off the MOSFET and switch the direction of the body diode, thereby providing an over charging and an over discharging protection functions.

摘要： A switch embedded integrated circuit for battery protection includes a MOSFET having a body diode, and a control logic circuit for switching the MOSFET and the direction of the body diode to control the charge current to and the discharge current from a battery. The control logic circuit turns off the MOSFET once any abnormal operation such as over-voltage and under-voltage happens, and turns on the MOSFET according to an OVPR threshold, an OVPR delay time, an UVPR threshold and an UVPR delay time. The OVPR threshold and the OVPR delay time are determined depending on the battery being coupled to a load or a charger, or floating.

摘要： A circuit and method are disclosed for providing smart protection to a battery pack against abnormal operation with an electrical switch. The battery cell of the battery pack is monitored to control the electrical switch. If abnormal operation occurs, the electrical switch will turn off to disconnect the battery cell. Once the abnormal condition disappears, the electrical switch will turn on and the battery cell will return to normal state.
